Cosmos SDK v0.44.1 Release Notes

This release introduces bug fixes and improvements on the Cosmos SDK v0.44 series.

The main bug fix concerns all users performing in-place store migrations from v0.42 to v0.44. A source of non-determinism in the upgrade process has been detected and fixed in this release, causing consensus errors. As such, v0.44.0 is not safe to use when performing v0.42->v0.44 in-place store upgrades, please use this release v0.44.1 instead. This does not impact genesis JSON dump upgrades nor fresh chains starting with v0.44.

Another bug fix concerns calling the ABCI Query method using client.Context. We modified ABCI queries to use abci.QueryRequest's Height field if it is non-zero, otherwise continue using client.Context's height. This is a minor client-breaking change for users of the client.Context.

Some CLI fixes are also included, such as:

• using pre-configured data for the CLI add-genesis-account command (#9969),
• ensuring the init command reads the --home flag value correctly (#10104),
• fixing the error message when period or period-limit flag is not set on a feegrant grant transaction #10049.

v0.44.1 also includes performance improvements, namely:

• IAVL update to v0.17.1 which includes performance improvements on a batch load #10040,
• Speedup coins.AmountOf(), by removing many intermittent regex calls #10021,
• Improve CacheKVStore datastructures / algorithms, to no longer take O(N^2) time when interleaving iterators and insertions #10026.

See the Cosmos SDK v0.44.1 milestone on our issue tracker for the exhaustive list of all changes.
